As the wireless channel is constantly changing, MIMO-OFDM eigenmode transmission is extremely vulnerable to the presence of feedback delay which is unavoidable in a practical system. Under such imperfect conditions, the inter-eigenmode interference can be removed through the use of the MMSE interference canceller. However, to the best of our knowledge, the performance of MIMO-OFDM eigenmode with MMSE...
Adaptive MIMO eigenmode transmission system is a promising candidate for future high data rate wireless systems. However under practical conditions when channel state information (CSI) is imperfect, the eigenbeams lose their orthogonality and inter-eigenmode interference occurs. No work so far has attempted to consider the effects of inter-eigenmode interference on the adaptive signaling algorithm...
